Hi,
when I register these mixer controls:
Line Playback Switch Line Playback Route Mono Playback Switch Mono Playback Route Phone Playback Switch Phone Playback Route Headphone Playback Switch Headphone Playback Route PCM Playback Switch PCM Playback Volume Line Bypass Capture Switch Line Bypass Capture Volume ADC Capture Route
Running "alsamixer" fails with:
ALSA lib simple_none.c:1218:(simple_add1) helem (MIXER,'Headphone Playback Switch',0,0,0) appears twice or more
It seems there are restrictions what kind of control name I can use for each control, but what restrictions? Are there better names for my output amplifiers? Each of it I can enable/disable (-> Switch) and select a source (-> Route) independently.
You can use "xxx Source" instead of "xxx Route", I guess, as a workaround.
